What a beautiful reception idea! :) Glass Spheres: These pretty bubbles are so popular right now. You can fill them with flowers for a day-wedding and with candles at night.

For one of your table options grouping floating candle vases together is a pretty option for a non-floral centerpieces. To add the "wow", tint the water in some of the vases a dark purple and some a light purple and float gold candles.
